Omnifaces 2.x fails when used in a Spring Boot environment with Weld

Question

Finally I successfully bootstrapped Weld in a Spring Boot environment as explained here. CDI works with no problem both for JSF using Mojarra and for Web Services using Jersey.

But now I encountered a problem when trying to include Omnifaces 2.6 in my application.

My application start fails with this message:

That will happen when Weld isn't actually initialized. Do you have a beans.xml? — BalusC, Jan 25 '18 at 07:24
Yes. As I said in my question CDI (Weld) works with no problem. Even if I call the failing sentence CDI.current().getBeanManager() in my code it returns correctly the BeanManager that when printed displays "Weld BeanManager for /Escola_/Users/beleta/workspace/EscolaSpringBoot/target/classes [bean count=39]". — Josep M Beleta, Jan 25 '18 at 08:16
Then it's initialized too late. Normally, it's initialized in a servlet container initializer which runs before a servlet context listener. I'm not sure how Spring Boot and all works, but if you really can't go around a servlet context listener in order to initialize Weld, then it should be registered before JSF's one. — BalusC, Jan 25 '18 at 08:59
Ok, thank you. I will try to change the initialization order and I'll come back. — Josep M Beleta, Jan 25 '18 at 10:32

Josep M Beleta · Answer 1 · 2018-02-15T23:34:59.450

As stated by @BalusC it was a problem of order of initialization.

I was using:

import org.jboss.weld.environment.servlet.Listener; 

@SpringBootApplication
public class MyApplication
{
  public static void main(String[] args)
  {
    SpringApplication.run(MyApplication.class, args);
  }

  @Bean
  public Listener weldListener()
  {
    return new Listener();
  }
}

So it was initialized as a servlet context listener that ran after JSF initialization.

I changed my code to use:

@Bean
public ServletContextInitializer weldServletContextInitializer()
{
  return new WeldServletContextInitializer();
}

instead of weldListener() where WeldServletContextInitializer is:

import javax.servlet.ServletContainerInitializer;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;

import org.jboss.weld.environment.servlet.EnhancedListener;
import org.springframework.boot.web.servlet.ServletContextInitializer;

public class WeldServletContextInitializer implements ServletContextInitializer
{
  private ServletContainerInitializer servletContainerInitializer;

  @Override
  public void onStartup(ServletContext servletContext) throws ServletException
  {
    ServletContainerInitializer servletContainerInitializer = getServletContainerInitializer();
    servletContainerInitializer.onStartup(null, servletContext);
  }

  private ServletContainerInitializer getServletContainerInitializer()
  {
    if (servletContainerInitializer == null)
      servletContainerInitializer = new EnhancedListener();

    return servletContainerInitializer;
  }
}

Now Omnifaces 2.x starts with no problem.

EDIT:

It is needed to initialize Omnifaces thru org.omnifaces.ApplicationInitializer, it is done in this bean:

@Bean
public ServletContextInitializer omnifacesServletContextInitializer()
{
    return new OmnifacesServletContextInitializer();
}

Where OmnifacesServletContextInitializer is:

import javax.servlet.ServletContainerInitializer;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;

import org.omnifaces.ApplicationInitializer;
import org.springframework.boot.web.servlet.ServletContextInitializer;

public class OmnifacesServletContextInitializer implements ServletContextInitializer
{
    private ServletContainerInitializer servletContainerInitializer;

    @Override
    public void onStartup(ServletContext sc) throws ServletException
    {
        ServletContainerInitializer servletContainerInitializer = getServletContainerInitializer();
        servletContainerInitializer.onStartup(null, sc);
    }

    private ServletContainerInitializer getServletContainerInitializer()
    {
        if (servletContainerInitializer == null)
            servletContainerInitializer = new ApplicationInitializer();

        return servletContainerInitializer;
    }
}

I've done the same modification and apparently it's working. But I notice that the org.omnifaces.ApplicationInitializer:onStartup is not called. Is it correct? — Gavi, Feb 12 '18 at 20:55
Yes, you are right. org.omnifaces.ApplicationInitializer:onStartup has to be called. I'll modify my answer to include this initialization. — Josep M Beleta, Feb 15 '18 at 23:25
Thank you. Just to understand all the process I'm trying to create a plain spring boot project with weld, jsf and omnifaces. All is working except for weld that is not scanning anything. But this is another story :( — Gavi, Feb 20 '18 at 21:44
